VoLTE Icon Samsung Galaxy S10. User Manual.
Hello guys! We’re going to tell you about the VoLTE icon Samsung. Have you ever wondered what it is actually and why this sign appears near your network signal icon from time to time? You’ve seen this icon if you’re using an LTE wireless connection on your Samsung Galaxy smartphone or just about any modern smartphone.
This is exactly what this article is about. Moreover, you will learn how to activate the LTE function and how to know if your phone supports LTE or not using different methods for that.
Now the world of technologies progresses extremely fast. By this moment practically every phone is equipped with VoLTE and LTE functions. So, if you have this function on your smartphone and, moreover, everyone has, why not learn what it is and how you can turn it on. These questions will be answered in the article. Besides, you will be given a short history of types of mobile connection which preceded LTE. You will learn what the benefits of using LTE are.
VoLTE Icon Samsung
In the picture, you can see the VoLTE Icon Samsung. The icon on the upper line right under the Samsung phone logo. It appears when the LTE function is activated. LTE activation in turn means that the calls will be carried out with the help of LTE.
Here you can see the meanings of galaxy phone symbols in case you don’t know some yet.
Older Generations of Telecommunications
Here’s a little historical review on the topic of generations of telecommunications that preceded LTE. There were Mobile Radio Telephone, 1G, 2G, and 3G before LTE appeared. Telecommunication signals are divided into 2 types: digital and analog. MRT and 1G were analog, after, more modern digital versions which are 2G and 3G were invented.
An analog signal is any continuous signal for which the time-varying feature of the signal is a representation of some other time-varying quantity.
A digital signal is a signal that is being used to represent data as a sequence of discrete values.
1G means the 1st generation of wireless cellular technology. It was presented in the 1980s. On the base of 1G, the first commercial network was launched in Japan in 1979 by NTT. Approximately 5 years later the network embraced all populations. This way, NTT became the first company whose network covered all the country.
2G (second-generation cellular network) was invented and launched in Finland in 1991 on the basis of the GSM standard (Global System for Mobile Communications).
GSM is a global standard of digital mobile communication with a division of channels by time and frequency.
2G exceeded the previous generations of telecommunications in many attitudes a lot. Digitally encrypted phone conversations became possible thanks to 2G. Usage of radio frequency band increased which meant more users could be engaged in 1 frequency band. What has the most important, text messages finally appeared?
Maximum speed per second increased as well. GPRS had 40kbits per second, new EDGE raised the bar to 384 bits per second.
In 2001 3G became available for purchase. By the moment of the launch, 3G offered only 144 bits per second. However, after a while, the speed rocketed to several Mbits per second. This was a breakthrough in the telecommunications sphere. Thanks to such a level of speed, many other functions became possible, for example, video conferencing and streaming.
This way, all the population got the possibility to those things that only really wealthy people could have before. By the way, the security characteristics improved much, too.
LTE (Long Term Evolution)
LTE was suggested in 2004 and in 2008 in Stockholm, the 1st public presentation was held. There LTE was introduced as an instrument of data connection through a USB modem. LTE also improved a lot comparing to the previous generations. However, LTE characteristics are not the same as 4G characteristics, that’s why LTE is often called 3.95 G, 4G LTE, and Advanced LTE.
So, here’s the list of LTE features:
- The maximum speed of download is 300Mbit per second and for upload, it is 75Mbit per second.
- Data transfer latency achieved its record value – 5ms.
- All frequency bands used by IMT systems under the ITU could be maintained by LTE.
- Spectrum flexibility went up to 1.4MHz, 3MHz, 5MHz, 10MHz, 15MHz, 20MHz.
Spectrum flexibility influences the possibility of deployment in differently-sized spectrum allocations and in diverse frequency ranges.
- The interface became much more convenient through its simplification.
Along with all the advantages of LTE, there were minuses, too. The fact is that GSM and UMTS (Universal Mobile Telecommunications System) standards supported nothing but circuit switching while LTE provides calls made with the help of packet switching.
Circuit switching is a method of implementing a telecommunications network in which two network nodes establish a dedicated communications channel (circuit) through the network before the nodes may communicate.
Packet switching is a method of grouping data that is transmitted over a digital network into packets.
The following methods were applied to fix the situation:
- Simultaneous Voice and LTE
- Circuit-switched fallback
- Single Radio Voice Call Continuity
VoLTE became the most common since it is flexible.
VoLTE (Voice Over LTE)
In 2012 in Dallas (Texas)VoLTE became available for purchase, as well as the VoLTE phone LG Connect 4.
VoLTE (Voice over Long-Term Evolution) is a high-speed wireless communication standard for mobile phones and data terminals, including Internet of things (IoT) devices and wearables.
Besides, VoLTE is also named as HD voice feature.
There are some improvements that differ VoLTE from the previous generations of communications:
- VoLTE has up to 3 times more voice and data capacity than older 3GUMTS and up to 6 times more than 2G GSM.
- VoLTE requires a smaller data amount and a smaller bandwidth thanks to the fact that it uses smaller packet headers.
- VoLTE engages a wider range of frequencies: up to 7kHz while the previous ones had only 3.5kHz.
By this moment VoLTE occupies a leading position on the market. Moreover, it is even a standard. There are more than 250 operators whose products support LTE and VoLTE and almost all phones have this feature.
Checking LTE or VoLTE on your phone
The list will show you how to learn if your smartphone has VoLTE or LTE though it is almost impossible that it doesn’t if you have a new model which was released later than 2016.
So, here’s how to check if your phone supports LTE or VoLTE:
- Ask your mobile operator about it (call or go to the local phone store)
- Look at the packaging of your SIM-card
- Check it in the Settings in the section of the network.
If you’re interested in Samsung volte phones, it is easy to check when choosing phones on the Internet, the presence of the VoLTE is always written in the description.
The VoLTE Icon on Samsung
To see if the Samsung VoLTE function is activated at the moment, you should check if there’s a VoLTE icon on the screen. It is always placed next to the Wi-Fi icon. There’s a picture of the icon higher. You can turn the mode through the settings.
When the function is activated and the icon presents on the screen, your calls are implemented with the help of VoLTE. The function gives a higher quality of sound.
Enabling the VoLTE service
To enable the VoLTE on android, you should do these actions:
- Put the SIM card in the smartphone
- Open the Settings
- Choose Connections option
- Then press on Mobile networks
- Choose the SIM card you need
- Choose LTE/3G/2G (Auto) button
Removing the VoLTE Icon on Samsung
The procedure of deleting the VoLTE icon can be made only with the help of transforming the basic settings of the smartphone. It is not safe, so it is better not to risk. However, the icon will disappear when you turn off the LTE function. It is possible to do through Settings. The algorithm was described in the previous paragraphs, so go up to learn it.
As you can see, telecommunication technologies have been modernized really much and fast. Since the 1970s they reached a new level of development approximately every 10 years. By this moment the most modern generation of mobile communications is 5G. It is actively used in many countries if we speak about developed ones, of course.
The main advantages of LTE are good quality of voice, more flexible frequencies, and the same cost.
